At least based on my uses, I agree that this would likely bring the most use of the now unused binding space in cores if-let. I can't think of any useful alternatives.
Syntactically though, one could worry that the additional bindings would be read as regular let bindings and worry about the language clarity. I don't have the distance of a naive Clojure reader to position myself there. I remember, that when I started learning Clojure, I thought that I could just use the vector for additional regular let bindings. I think that I read the doc string first which would explain why I expected conditional evaluation only for the first binding. The other problem is that design wise, it opens up the possibility to abuse the vector for regular let bindings, a la "These exprs are going to evaluate to logical truth anyways, as long as I have other things to worry about, they will get their own let later." Clojures design often helps writing clean code and this limitation could be seen as (very small) part of that. I must also say that I have rarely used or seen more than two nested if-lets. In such a case one should usually consider refactoring.
